Today Basque holds co-official language status in the Basque regions of Spain: the full autonomous community of the Basque Country and some parts of Navarre. Basque has no official standing in the Northern Basque area of France, and French citizens are barred from using Basque in a French court of law.

By contact with nearby peoples, Basque has borrowed words from Latin, Spanish, French, Gascon and others but accepted fewer than Indo-European languages. Some claim that many of its words come from Latin, but phonetic evolution has made many of them now appear as if they were native words, e.g. lore ("flower", from florem), errota ("mill", from rotam, "[mill] wheel"), gela ("room", from cellam).

Basque is written with the Latin alphabet. The universal special letter is ñ, which is pronounced like the n in onion, and ç and ü are also used. Basque does not use c, q, v, w, y except for loanwords and are not considered part of the alphabet. Also, x is pronounced as a sh, as in shine.
